L68.2 ICD-10-CM Code: Localized hypertrichosis

Coding instructions

Official Tabular Instructional Notes: the inclusion, exclusion and sequencing notes published for L68.2 in the official ICD-10-CM tabular list, quoted as published.

Source: CMS/CDC — ICD-10-CM Tabular ListRelease: FY2026Effective: October 1, 2025

Notes without a marker are published on L68.2 itself; “inherited from” names the category or block whose note applies here.

Coder workflow for L68.2

MedCoder structured workflow — derived from this code’s own official record

Before you code L68.2

1. Check the Excludes1 note: if the documentation supports a condition named there, do not simply proceed with L68.2. Excludes1 conditions are not reported together with this code unless the record shows they are unrelated (Guidelines I.A.12.a).

   See the official tabular notes

Choose the right path

1. Does the documentation support a condition named in L68.2’s Excludes1 note?
   Yes → Do not simply proceed: review the excluded code. Both are reported only when the record shows the two conditions are unrelated.
   No → Continue.

   ReviewQ84.2, Q84

Consider L68.2. Then confirm the code is valid for the date of service in the Verify section.

Documentation check

The provider’s diagnostic statement

Codes are assigned from the provider’s documented diagnosis, not from clinical criteria, test values or a medication list (Guidelines I.A.19).

Official instructions as workflow

• Excludes1 — check before selecting L68.2(3 notes)

  Coding workflow: If the documentation supports a condition named in this note, do not simply proceed with L68.2: the two are not reported together. The one exception is when the record shows the two conditions are unrelated to each other.

Coding decision scenarios

Pattern scenarios for this code’s structure — decision rules, not clinical cases

Every row is derived from this code’s own record — its title, tabular notes, 7th-character family and same-category siblings — with fixed MedCoder wording; nothing is inferred about a patient. The official notes and guideline text are in the sections each row links to, and they control.

Indexed Clinical Terms (1)

Official source data — entries quoted as published, in the Index’s own lookup phrasing

Clinical term phrases from the official ICD-10-CM Index to Diseases and Injuries that map to this code. These are alphabetic-index entries shown as the Index writes them — lookup phrasing, not necessarily the wording of a final diagnosis.

• Hypertrichosis, localized

Don’t confuse L68.2 with…

MedCoder analysis — pairs from this code’s official notes, distinctions written by MedCoder

The codes most likely to be picked instead of L68.2 — named in its own official notes, or sharing its laterality or encounter family — with what separates them and which documentation moves the case. Each links to the full comparison.

• Q84.2— Excludes1 conflict (Excludes1 — generally not reported together)

  Not coded here — the tabular list excludes this pair for the same encounter.

  Not reported together with this code, except where the two conditions are documented as unrelated.

  What moves you there: Documentation of congenital hypertrichosis moves the case to Q84.2; the two are not reported together unless documented as unrelated.

  Full comparison: L68.2 vs Q84.2 →

• Q84— Excludes1 conflict (Excludes1 — generally not reported together)

  Not coded here — the tabular list excludes this pair for the same encounter.

  Not reported together with this code, except where the two conditions are documented as unrelated.

  What moves you there: Documentation of congenital hypertrichosis moves the case to Q84; the two are not reported together unless documented as unrelated.

  Full comparison: L68.2 vs Q84 →

• L68.9— Specificity relationship (Review)

  Overlapping diagnoses in the same category.

  Overlapping codes in the same category — the documentation decides which is the more specific fit.

  What moves you there: A record that documents no more than “Hypertrichosis, unspecified” takes L68.9; specificity in the record moves it back here.

  Full comparison: L68.2 vs L68.9 →

Relationships are read from this code's own official notes, its laterality siblings and its encounter family; the wording of each distinction is MedCoder editorial, and the documentation named in each “what moves you there” line is the official note phrase or sibling title itself.

Relationships & Classification

MedCoder structured relationships — computed from published CMS and AHRQ datasets

MS-DRG Grouper Relationships (FY2026)

Potential MS-DRG participation — not a DRG assignment.

FY2026 MS-DRG: not on the CMS CC/MCC list — as a secondary diagnosis this code does not change MS-DRG severity for that release.

Named in the grouper logic of 2 MS-DRGs: DRG 606 (MDC 09), DRG 607 (MDC 09).

From the CMS MS-DRG Definitions Manual (Appendices B and C). Actual DRG assignment depends on the complete claim.

Same Index main term, other category

The ICD-10-CM Index to Diseases and Injuries files this code under the main term “Hypertrichosis”; these codes share that main term but sit in a different category of the Tabular List.

H02.861 — Hypertrichosis of right upper eyelid (eyelid, right, upper), H02.862 — Hypertrichosis of right lower eyelid (eyelid, right, lower), H02.863 — Hypertrichosis of right eye, unspecified eyelid (eyelid, right), H02.864 — Hypertrichosis of left upper eyelid (eyelid, left, upper), H02.865 — Hypertrichosis of left lower eyelid (eyelid, left, lower), H02.866 — Hypertrichosis of left eye, unspecified eyelid (eyelid, left), H02.869 — Hypertrichosis of unspecified eye, unspecified eyelid (eyelid), Q84.2 — Other congenital malformations of hair (lanuginosa)
